Fillis Fly Screens Windows 150x300cm – Fibreglass Window Screen Mesh for Insects
Product description
What it is
Fillis Fly Screens are a DIY-friendly window screening solution made from durable fibreglass fabric. Supplied in a generous 150x300cm size, the grey mesh is designed to keep mosquitoes, bees and other insects out while allowing fresh air to flow through. The kit includes a cleaning brush and roller, plus straightforward instructions, so you can install and maintain the screen with relative ease.
What problem it solves
If you want to enjoy outdoor air without the nuisance of bugs, this fibreglass screen provides a practical barrier at windows and doors. It’s designed for long-term use, with a fabric that is scratch-resistant, tear-resistant and flame-retardant. It’s suitable for frequent openings and closures, such as living rooms, kitchens or access to balconies.

Material and build quality
On paper, fibreglass screen fabric offers durability and flexibility for cutting to size. The material is described as scratch-resistant and tear-resistant, which suggests a longer lifespan compared with some cheaper mesh options. It’s also washable and reusable, which helps with sustainability and value over time.
How to install and maintain


The kit is intended for simple DIY installation. You can cut the fabric to the exact size using a knife or scissors and then fit it into the frame with the included roller and cleaning brush. The supplied instructions should guide you through the process. Regular maintenance involves cleaning the mesh to prevent dust build-up and keeping the edges properly tensioned.

Best use cases
This screen is shown as suitable for various window types—windows, skylights, hinged or sliding doors, and balcony doors. It’s particularly handy where there are children’s rooms, living areas or kitchens, and where you want to reduce insect presence without blocking light or airflow.
Strengths and what could be better
On the plus side, the ability to cut to size makes it versatile for many window shapes and sizes, and the long-term pest barrier remains notable. The inclusion of a cleaning brush and roller is a practical touch for ongoing maintenance. A potential limitation is that the 150x300cm sheet is a single fixed size, if your opening differs substantially, additional adjustments or multiple sheets might be necessary. Also, while the material is described as durable, performance in very windy conditions or in areas with heavy debris isn’t specified.

Who it’s for
If you prioritise a practical, cut-to-fit insect screen that’s easy to install and reusable, this Fillis solution could fit. It may appeal to homeowners or renters looking to improve comfort in living spaces and kitchens without resorting to chemical repellents.


When it makes sense to buy
Consider this product if you have a window or door opening that fits roughly 150x300cm and you want a straightforward, DIY-friendly screen that you can personalise to the exact size. It’s sensible if you’re aiming for a durable, reusable mesh that helps keep bugs out while allowing air flow.

When you might hesitate
If your opening isn’t close to the 150x300cm dimensions, you may need to adapt or source an alternative size. If you require a screen for very irregular shapes or extremely windy conditions, the stated capabilities might not fully address your needs.
What to check before buying
- Confirm your opening dimensions are compatible with 150x300cm or can be cut to fit.
- Consider whether you need a frame for tensioning the mesh, as the base description focuses on the fabric and installation tools.
- Look at maintenance expectations, while washable, ensure you’re comfortable with regular cleaning to maintain visibility and airflow.

Practical comparison and context


This approach sits between simple disposable screens and premium retractable systems. It suits buyers who want a cost-effective, cut-to-fit option with tangible long‑term use, rather than a high-end, motorised or framed screen. If you prioritise a fixed, custom-cut solution with included tools and a straightforward install, it may be a sensible middle-ground choice.
